OILER iron HIGH-SPEED non'rnas.

Application and December aw, 1922. Seria1 No.-609,291.

This invention relates to :oil cups, and

particularly to a cup for distributing oil.

in a predetermined quantity to a spindle running athigh speed, and has-for an object liOwpI'OVldG the cup with a measure for predetermining the quantity. of lubricant supplied to the :cup, and with means for preventing the supply of lubricant to the cup except through said measure.

It is intended to beoapplied'to oil-cups shown, described and claimed in United States Letters Patent No. 776,262, dated November 29, 1904, and United States Letters Patent No. 784,280, dated March 7, 1905, with anobjectin view of providing a cup comprising a casing having a plug secured thereto for protecting the body of absorbent material in the casing, which plug is provided with an opening and a measure depending'therefrom and in communication with the bottom of the casing.

Another objectisto providea cup having a plug with an opening theretl1rough,-and provided with a sprin actuated cover for automatically closingthe opening.

Apractical embodiment of my invention is represented in the. accompanying drawing,

in which Fig. 1 represents a side elevation of my improved oil cup "as it appears when applied to a routing cutter. V

The casing of the oil cup is denoted 4,

and is herershown ascylindrical in form and adapted to be held clasped :to the bearing 3 by means of spring arm 5 which-may be swung into and out of engagement with thecasing 4 to lock and release it.

h A plug 6 is inserted within the casing 4 and provided with a a peripheral flange 7 which rests upon the upper edge of the casing. This plug has an opening 8 therethrough, in which a tube 9. is fittedto depend therefrom. A cover 10 isupivotally secured to the plug 6 by means of a screw :11 having a threaded engagement withthe plug. H

The. cover 10 has an inlet 12 which is arranged to be moved into and out of register with theitube 9. This. cover is normally held with its inlet 12 out of register with the tube 9 by means of a spring 13 housed in a recess 14 in the plug 6, one end of which spring is secured at 15 in the plug,

and the other end at 16 in the cover. The inlet 12. in the cover 10 is manually brought into register with the tube 9 by means of a lug 17 extending beyond theperiphery of the cover. The plug is securedin position in the casing by means of a screw 18, which screw is arranged in position to be engaged by the lug 17 when the inlet 12 and tube '9 are in alinement.

A body of absorbing material 19 is preferably made to fit anlflsubstantially fill the interior of thecasing 4, with the exception of a groove or perforation 20 extending longitudinally of. the bod in the present instance, atone side-of the ody,iand prefer ably at the side farthest from the outlet 21 through which the oil is conducted from the absorbent material 19 to the spindle 1.

The perforation or groove 20 is intendedto receive the tube 9 which is in communication at its bottom with the body-of absorbent material'within the casing 4.

. The capacity of the tube 9 is predetermined, and the tube is made of such dimension as to hold the quantityof lubricant which is found to be most satisfactory for lubricating the spindle for a predetermined length of time during its operation.

For example, if it be found that one drop of lubricant will be sulficient to lubricate the spindle for a period of ten hours run and it be desired to replenish the supply after each days run, then the measure 9 would have a capacity of one drop and all that would be required to replenish the oil cup would be to quickly fill the measure 9 before an opportunity is given for the oil to be absorbed by the absorbent body. The charge of oil as soon as the cup is closed will be gradually picked up by the body of absorbent materials within the cup and will be gradually transmitted to the spindle by means of a Wick 22 of absorbent material which is intended to pass from contact with the spindle 1 through the tubular outlet 21 and through a perforation 23, extending transversely through the body of absorbent material 19.

By the arrangement of the plug and cover on the casing, it is evident that the oil admitted to the absorbent material must ass through the tube 9 and to the bottom 0 the casing, thereby preventing an operator from carelessly supplying lubricant to the top of the absorbent material where it will be immediately carried off by the wick to the spindle and which would result in an inadequate supply from the run. It is highly desirable that the supply of lubricant be passed through the measure to the bottom of the casing so that it will be caused to flow upwardly and thoroughly saturate the absorbent material before it passes through the wick to the spindle.

It is evident that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the s irit and scope of my invention; hence, I 0 not intend to be limited to the specific details herein shown and described, except as they may be included in the claims. 7 i

What I claim is:

1. The combination withan oil cup comprising, a casing, a body of absorbent material titted Within the casing, and a wick ot' absorbent material leading from the body of absorbent material through the casing, of a plug inserted in and secured to the casin for protecting the absorbent material, sai

plug having a measure depending therefrom for the reception of a charge of lubricant of predetermined quantity, and a cover provided with an inlet arranged to be moved into register with said measure in the plug,

said cover normally closin the measure.

2. The combination wit an oil cup comprisin a casing, a body of absorbent materialt absorbent material leading from the body of absorbent material through the casing, of a plug inserted in and secured to the casing for protecting the absorbent material, said plug having a measure depending therefrom tor the reception of a charge of lubricant of predetermined quantity, and a spring actuated cover provided with an inlet arranged to be moved into register with said measure in the plug, said cover normally closin the measure. i

3. he combination with an oil cup comprising, a casing, a body of absorbent material fitted within the casing, and a wick of absorbent material leading from the body of absorbent material through the casing, of a plug inserted in and secured to the casing for protecting the absorbent material, said plug havin a tubular measure depending therefrom $01 determining the amount of an oil charge, and a cover movable to normally close said measure.

4. The combination with an oil cup comprising, a. casing, abody of absorbent material fitted within the casing, and a wick of absorbent material leading from the body of absorbent material through the casing, of a plug inserted in and secured to the casin for protecting the absorbent material, sai plug having a tubular measure depending therefrom for determining the amount of an oil charge, said measure being embeddedin the body of absorbent material, and a spring actuated cover movable to normally close the measure.

In testimony, that I claim the foregoing as my invention, I have signed my name this 18th day of December, 1922. i
